Below you will find 8 options to make your character more interesting and detailed. Personally I would recommend using all options at the same time, since they are easy to implement and they provide interesting story tools for your character, by creating keywords for him/her/it and rewards you for acting out the personality and background of your character.

These options can be chosen individually, but some of them work better when combined. By including them all you will see, that they compliment each other, since each option covers different aspects of your character.

A set of character responses to situations or questions (or anything else :D), trying to create an outline to understand what type of an answer or response your character (or an NPC for that matter) can give.

Character
quirks can be little exercises in roleplaying that make things fun for
the player. They can also have major game implications if the character
is faced with a dilemma where two of their values come in conflict. Here
are 101 player character quirks that can be used in many different
types of settings. These quirks vary from small quirks (small effect on
game play) to big quirks (potentially large effect on game play).

The Creator had created Impthus out of the very essence of light itself. And so do all of his fellow followers. The Athlran glow endlessly, no matter where they are. They have a pair of white wings and their form radiates bright light, as the High Heaven itself.

At the beginning of life, before the Living World was created, the Creator had created only Felenthur and Impthus, that he made them both as brothers. One with the heart of darkness and one with the heart of light. Impthus was given the High Heaven with the Orb of Light. While, Felenthur was given the scorching plains, where soon, he transformed the plains into the Burning Hell as soon as he managed to made a plea to the Creator. A plea which he asked to create an ally for him. Thus, the Demon Princess and Princesses were born into the Burning Hell.

In a world where mutant powers are real, not everyone can be a Storm, Cyclops or Wolverine. Here's a list of super powers for those who were a little less lucky. They probably won't want to be sharing them anytime soon.

Tripping over the Golden Bough

Nearly every primitive culture has had rituals and celebrations to guarantee the proper passage of the seasons and to ensure the fertility of crops and animals. Oversight of these ceremonies was generally the provenance of local kings or priests.

Suppose that the adventurers dispatch one of these fellows. The local peasants may become hysterical, fearing famine and death will stalk the land. Alternatively, they may want one of the new heroes to become king. For a while, this can be a good thing, but the first time that the crops fail, the superstitious locals will want to sacrifice their new leader.
